My raspberries last year had a lot of tiny white worms in them. How can I prevent them from coming this year? Thank you. CF
I sounds like you’ve got some Spotted Wing Drosophila, a fruit fly type insect. The worms are the larvae od of the fly. Start spraying before they show up with Spinosad, and organic insecticide. We sell the Bonide version called Captain Jack’s Dead Bug Brew. Just follow the directions on the package. Start right away as they are attracted to ripe berries.
